The Trekker Lounge 25 almost seems like a frivolous luxury until you arrive at camp and see someone comfortably kicked back in one--it certainly beats sitting on a hard rock or damp rotting log. For a couple of ounces of pack weight you can convert any large size Thermarest pad into a camp chair with adjustable backrest. Thermarest recently added an attached fleece Stuff-It Pillow for a little contouring around your neck and occipital lobes. Frivolous luxury? Hardly. After a long haul up the trail this is a rightful rest everyone deserves.
